Queen Square is a garden square in the Bloomsbury district of the London Borough of Camden, England. Queen Square was originally constructed between 1716 and 1725. It was formed from the garden of the house of Sir John Cutler baronet (1608-1693), whose last surviving child, Lady Radnor, died in 1697 leaving no issue. It was left open on one side for the landscape formed by the hills of Hampstead and Highgate.
